I had thought I would by FR before it came out because I love building and I wanted to be able to make apartments, but then the bug reports flooded in. I've been tracking them ever since, and the pack is still not fixed enough for me to consider buying it. (Setting aside the fact that I'm not buying packs at all these days as a form of feedback to EA.) For one thing, I have a long-running save that I won't risk corrupting. I think maybe this pack works better for people who start fresh saves on a regular basis. But, that's just a theory since we're still not 100% sure about exactly what conditions trigger the corruption bug.
There are other bugs as well that make key features of the pack pointless, such as landlords not getting paid.
Bottom line is, I'm not going to buy a pack knowing that I can't use it as intended or that I'd have to use a bunch of workarounds (which I'd probably forget about half the time) to make it function properly. It's not worth it to me to buy the pack and then turn off or avoid using certain features that I paid for in an effort to prevent a bug that could destroy my game or to make badly tuned features less annoying. One day, if they fix the corruption bug and also if I'm feeling less salty about EA in general, maybe I'll buy it at 50-60% off. But, I see neither of these things on the horizon right now.
